RESUMO

BACKGROUND: While adult outcome in autism spectrum disorder (ASD) is generally measured using socially valued roles, it could also be understood in terms of aspects related to health status - an approach that could inform on potential gender differences. METHODS: We investigated gender differences in two aspects of outcome related to health-status, i.e. general functioning and self-perceived health status, and co-occurring health conditions in a large multi-center sample of autistic adults. Three hundred and eighty-three participants were consecutively recruited from the FondaMental Advanced Centers of Expertise for ASD cohort (a French network of seven expert centers) between 2013 and 2020. Evaluation included a medical interview, standardized scales for autism diagnosis, clinical and functional outcomes, self-perceived health status and verbal ability. Psychosocial function was measured using the Global Assessment of Functioning scale. RESULTS: While autistic women in this study were more likely than men to have socially valued roles, female gender was associated with poorer physical and mental health (e.g. a 7-fold risk for having three or more co-occurring physical health conditions) and a poorer self-perceived health status. Psychosocial function was negatively associated with depression and impairment in social communication. Half of the sample had multiple co-occurring health conditions but more than 70% reported that their visit at the Expert Center was their first contact with mental health services. CONCLUSIONS: To improve objective and subjective aspects of health outcome, gender differences and a wide range of co-occurring health conditions should be taken into account when designing healthcare provision for autistic adults.

RESUMO

Associations between fetal exposure to antidepressants and neonatal hypotonia were studied using VigiBase and the French PharmacoVigilance Database. We identified significant associations between neonatal hypotonia and clomipramine, venlafaxine, and imipramine. Reports from the French database implicated prolonged fetal exposure. Neonatal hypotonia may be associated with in utero exposure to antidepressants.

RESUMO

Many children develop a characterized sleep disorder, sometimes with severe consequences. Behind the term "insomnia", there is a wide variety of disorders, causes and psychopathological contexts to which the clinician will have to adapt for optimal management, from babies to pre-adolescents.

RESUMO

Reexperiencing symptoms in adolescent Post-Traumatic Stress Disorder (PTSD) are characterized by the apparition of vivid intrusive images of the traumatic event. The emergence of these intrusions is thought to be related to a deficiency in context processing and could then be related to hippocampal alterations. The hippocampus is a complex structure which can be divided into several subfields, namely, the Cornu Ammonis (CA1, CA2, and CA3), the subiculum, and the dentate gyrus (DG). As each subfield presents different histological characteristics and functions, it appears more relevant to consider hippocampal subfields, instead of only assessing the whole hippocampus, to understand the neurobiology of PTSD. Hence, this study presents the first investigation of structural alterations within hippocampal subfields and their links to reexperiencing symptoms in adolescent PTSD. Hippocampal subfields were manually delineated on high-resolution MRI images in 15 adolescents (13-18 years old) with PTSD and 24 age-matched healthy controls. The volume of the region CA2-3/DG region was significantly smaller in the PTSD group compared to controls in both hemispheres. No other significant difference was found for other subfields. Moreover, the volume of the left CA2-3/DG was negatively correlated with the intrusion score (as measured by the Impact of Events Scale-Revised) in the PTSD group. To conclude, an alteration in the hippocampal subregion CA2-3/DG, known to resolve interferences between new and similar stored memories, could participate in the apparition of intrusive trauma memories in adolescents with PTSD.

RESUMO

We proposed to explore the functional brain changes during a self-reference processing (SRP) task in adolescents with sexual abuse-related post-traumatic stress disorder (N = 10), compared with healthy adolescents (N = 10). While patients showed no behavioral disturbances in (SRP), they exhibited changes in activity and connectivity in regions involved in emotional regulation (amygdala and dorsal prefrontal cortex) and semantic memory (temporal and ventrolateral prefrontal regions). These preliminary results suggest that these alterations may have an effect on self-esteem which may contribute to a possible retention and impairment of symptoms in adulthood.

RESUMO

Recent research suggests that fetal exposure to antidepressants (ADs) is significantly associated with fetal death, including stillbirth. However, there has been limited investigation into the timing of AD exposure during pregnancy, the specific effect of each drug, and the possibility of indication bias. To address these gaps in knowledge, we conducted a systematic review of literature and disproportionality analyses using the WHO Safety Database (VigiBaseⓇ). The systematic review provided evidence for increased risks of fetal death with exposure to any selective serotonin reuptake inhibitor (SSRI) at any time of pregnancy, stillbirth with exposure to any AD during the first trimester, and stillbirth with exposure to any SSRI during the first trimester. Disproportionality analyses revealed significant associations with citalopram, clomipramine, paroxetine, sertraline, and venlafaxine. Combining both sets of results, we conclude that exposure to ADs, especially during the first trimester of pregnancy, seems to be associated with fetal mortality, and that ADs with highest placental transfer may be particularly involved. Further research should investigate the links between ADs during early pregnancy and fetal mortality.

RESUMO

The long-described atypicalities of memory functioning experienced by people with autism have major implications for daily living, academic learning, as well as cognitive remediation. Though behavioral studies have identified a robust profile of memory strengths and weaknesses in autism spectrum disorder (ASD), few works have attempted to establish a synthesis concerning their neural bases. In this systematic review of functional neuroimaging studies, we highlight functional brain asymmetries in three anatomical planes during memory processing between individuals with ASD and typical development. These asymmetries consist of greater activity of the left hemisphere than the right in ASD participants, of posterior brain regions-including hippocampus-rather than anterior ones, and presumably of the ventral (occipito-temporal) streams rather than the dorsal (occipito-parietal) ones. These functional alterations may be linked to atypical memory processes in ASD, including the pre-eminence of verbal over spatial information, impaired active maintenance in working memory, and preserved relational memory despite poor context processing in episodic memory.

RESUMO

BACKGROUND: The prescription of antidepressant drugs during pregnancy has been steadily increasing for several decades. Meta-analyses (MAs), which increase the statistical power and precision of results, have gained interest for assessing the safety of antidepressant drugs during pregnancy. OBJECTIVE: We aimed to provide a meta-review of MAs assessing the benefits and risks of antidepressant drug use during pregnancy. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a literature search on PubMed and Web of Science databases was conducted on 25 October, 2021, on MAs assessing the association between antidepressant drug use during pregnancy and health outcomes for the pregnant women, embryo, fetus, newborn, and developing child. Study selection and data extraction were carried out independently and in duplicate by two authors. The methodological quality of included studies was evaluated with the AMSTAR-2 tool. Overlap among MAs was assessed by calculating the corrected covered area. Data were presented in a narrative synthesis, using four levels of evidence. RESULTS: Fifty-one MAs were included, all but one assessing risks. These provided evidence for a significant increase in the risks for major congenital malformations (selective serotonin reuptake inhibitors, paroxetine, fluoxetine, no evidence for sertraline; eight MAs), congenital heart defects (paroxetine, fluoxetine, sertraline; 11 MAs), preterm birth (eight MAs), neonatal adaptation symptoms (eight MAs), and persistent pulmonary hypertension of the newborn (three MAs). There was limited evidence (only one MA for each outcome) for a significant increase in the risks for postpartum hemorrhage, and with a high risk of bias, for stillbirth, impaired motor development, and intellectual disability. There was inconclusive evidence, i.e., discrepant results, for an increase in the risks for spontaneous abortion, small for gestational age and low birthweight, respiratory distress, convulsions, feeding problems, and for a subsequent risk for autism with an early antidepressant drug exposure. Finally, MAs provided no evidence for an increase in the risks for gestational hypertension, preeclampsia, and for a subsequent risk for attention-deficit/hyperactivity disorder. Only one MA assessed benefits, providing limited evidence for preventing relapse in severe or recurrent depression. Effect sizes were small, except for neonatal symptoms (small to large). Results were based on MAs in which overall methodological quality was low (AMSTAR-2 score = 54.8% ± 12.9%, [19-81%]), with a high risk of bias, notably indication bias. The corrected covered area was 3.27%, which corresponds to a slight overlap. CONCLUSIONS: This meta-review has implications for clinical practice and future research. First, these results suggest that antidepressant drugs should be used as a second-line treatment during pregnancy (after first-line psychotherapy, according to the guidelines). The risk of major congenital malformations could be prevented by observing guidelines that discourage the use of paroxetine and fluoxetine. Second, to decrease heterogeneity and bias, future MAs should adjust for maternal psychiatric disorders and antidepressant drug dosage, and perform analyses by timing of exposure.

RESUMO

In a recent study on visual episodic memory (Desaunay, Clochon, et al., 2020), we have shown event-related potentials (ERPs) differences associated with priming (150-300 msec), familiarity (350-470 msec), and recollection (600-700 msec), in young people with autism spectrum disorders (ASD) compared with typical development (TD). To go further into the study of the processes of storage and retrieval of the memory trace, we re-analyzed Desaunay, Clochon, et al's data using time-frequency analysis, that is, event-related synchronization and desynchronization (ERS/ERD). This allows a decomposition of the spectral power within frequency bands associated with these ERPs. We focused both on the same time windows and the same regions of interest as previously published. We mainly identified, in ASD compared with TD, reduced ERS in low-frequencies (delta, theta) in early time-windows, and non-significant differences in ERD in higher frequencies (alpha, beta1) in all time-windows. Reduced ERS during recognition confirmed previously reported diminution of priming effects and difficulties in manipulation and retrieval of both semantic and episodic information. Conversely, preserved ERD corroborates a preservation of memory storage processes. These observations are consistent with a cognitive model of memory in ASD, that suggests difficulties in cognitive operations or executive demand at retrieval, subsequent to successful long-term storage of information. LAY SUMMARY: We assessed the EEG synchronization and desynchronization, during visual episodic recognition. We observed, in youth with Autism, reduced synchronization in low-frequencies (delta, theta), suggesting reduced access to and manipulation of long-term stored information. By contrast, non-significant differences in desynchronization at higher frequencies (alpha, beta frequency bands), that support long-term stored semantic and episodic information, suggested preserved memory traces.

RESUMO

Autism spectrum disorder (ASD) are neurodevelopmental conditions characterised by deficits in social communication and interaction and repetitive behaviours. Maternal immune activation (MIA) during the mid-pregnancy is a known risk factor for ASD. Although reported in 15% of affected individuals, little is known about the specificity of their clinical profiles. Adaptive skills represent a holistic approach to a person's competencies and reflect specifically in ASD, their strengths and difficulties. In this study, we hypothesised that ASD individual with a history of MIA (MIA+) could be more severely socio-adaptively impaired than those without MIA during pregnancy (MIA-). To answer this question, we considered two independent cohorts of individuals with ASD (PARIS study and FACE ASD) screened for pregnancy history, and used supervised and unsupervised machine learning algorithms. We included 295 mother-child dyads with 14% of them with MIA+. We found that ASD-MIA+ individuals displayed more severe maladaptive behaviors, specifically in their socialization abilities. MIA+ directly influenced individual's socio-adaptive skills, independent of other covariates, including ASD severity. Interestingly, MIA+ affect persistently the socio-adaptive behavioral trajectories of individuals with ASD. The current study has a retrospective design with possible recall bias regarding the MIA event and, even if pooled from two cohorts, has a relatively small population. In addition, we were limited by the number of covariables available potentially impacted socio-adaptive behaviors. Larger prospective study with additional dimensions related to ASD is needed to confirm our results. Specific pathophysiological pathways may explain these clinical peculiarities of ASD- MIA+ individuals, and may open the way to new perspectives in deciphering the phenotypic complexity of ASD and for the development of specific immunomodulatory strategies.

RESUMO

OBJECTIVE: To validate a French version of the Family Assessment Device (FAD), a well-known self-report questionnaire assessing family functioning in clinical and research settings. METHODS: A French adaptation of the FAD was administered to 3 groups of subjects: a nonclinical group (n = 115), relatives of psychiatric patients (n = 102), and medical patients and their relatives (n = 106). Temporal stability was assessed by test-retest intraclass correlations. Internal consistency was measured by Cronbach alpha reliability coefficients. Discriminant validity was explored, comparing the scores of the 3 groups, using a covariance analysis (ANCOVA). The dimensional structure of the instrument was explored using a principal component analysis, with promax oblique rotation, on the entire sample. RESULTS: The French FAD showed good temporal stability and good discriminant validity across groups. Internal consistency was satisfactory only for the General Functioning (GF) subscale. Factor analysis yielded a 3-factor model. The GF subscale was highly correlated with all of the other subscales. CONCLUSIONS: The French version of the FAD provides a valuable tool for assessing family functioning. However, our study failed to identify the theoretical structure of the FAD and suggests that the GF subscale could be used as a better overall indicator of family functioning.

RESUMO

BACKGROUND: Bullying, the most prevalent form of abuse among adolescents, is associated with emotional and behavioural problems as well as psychiatric morbidity. Moreover, it has been shown that adolescents with previous mental health problems are at increased risk of being bullied and that the psychopathological repercussions of bullying are greatest among them. However, little is known about the experience of bullying in adolescents receiving treatment from mental health services. The aim of this study was to explore the subjective experience of bullying in adolescents receiving mental health care. METHODS: The study was developed in the context of a French multicentre research program and employed an exploratory phenomenological approach. A purposeful sampling strategy was used to select adolescents who had experienced bullying (according to the Olweus criteria) and who were able to relate their experiences clearly. In-depth, semistructured interviews with participants were conducted; written transcriptions of these interviews were analysed using thematic analysis. RESULTS: Twenty-one adolescents (age range: 12-17 years; 13 girls) participated in the study. The analysis indicated a three-axis structure: (1) negative emotions and violent feelings, describing adolescents' fear, sadness, aggression against themselves, and generalized mistrust; (2) isolation and loneliness, underlining the need to take refuge within oneself and the experiences of rejection, helplessness, and secret-keeping; and (3) self and identity repercussions, including experiences of shame and lowered self-esteem, identity questions, and a vision of bullying as a life experience. CONCLUSIONS: The results of this study may have practical implications for clinicians: (1) a situation of bullying should be sought when an adolescent is seen for unexplained externalized behavioural misconduct; (2) low levels of emotional expression in a bullied adolescent may warn about associated self-harm; (3) a bullied adolescent's tendency to hide this situation from his or her parents may reflect underlying family-related vulnerability; and (4) the phenomenological analysis showed potential particularities in the assumptive world of these adolescents and suggested that relationality may play a crucial role in their experiences. These results suggest incentives to design specific individual and group therapeutic interventions for bullied adolescents with significant levels of social withdrawal, including family support. Additional research is necessary to improve our understanding of the psychopathological and intersubjective aspects of bullying in adolescents.

RESUMO

BACKGROUND: Autism spectrum disorder (ASD) is associated with atypical neural activity in resting state. Most of the studies have focused on abnormalities in alpha frequency as a marker of ASD dysfunctions. However, few have explored alpha synchronization within a specific interest in resting-state networks, namely the default mode network (DMN), the sensorimotor network (SMN), and the dorsal attention network (DAN). These functional connectivity analyses provide relevant insight into the neurophysiological correlates of multimodal integration in ASD. METHODS: Using high temporal resolution EEG, the present study investigates the functional connectivity in the alpha band within and between the DMN, SMN, and the DAN. We examined eyes-closed EEG alpha lagged phase synchronization, using standardized low-resolution brain electromagnetic tomography (sLORETA) in 29 participants with ASD and 38 developing (TD) controls (age, sex, and IQ matched). RESULTS: We observed reduced functional connectivity in the ASD group relative to TD controls, within and between the DMN, the SMN, and the DAN. We identified three hubs of dysconnectivity in ASD: the posterior cingulate cortex, the precuneus, and the medial frontal gyrus. These three regions also presented decreased current source density in the alpha band. CONCLUSION: These results shed light on possible multimodal integration impairments affecting the communication between bottom-up and top-down information. The observed hypoconnectivity between the DMN, SMN, and DAN could also be related to difficulties in switching between externally oriented attention and internally oriented thoughts.

RESUMO

Background: Psychopathological models of adolescent borderline personality disorder (BPD) suggest that non-suicidal self-injuring (NSSI)-a particularly frequent symptom in girls-may constitute a way of coping with distress resulting from interpersonal concerns they typically experience as a developmental psychopathological feature. Objectives: Our objective was to investigate the relationship in BPD female adolescents between NSSI and the Sidney Blatt two-polarities model of personality development, which focuses on the psychological processes of interpersonal relatedness and self-definition. Methods: The study was conducted within the European Research Network on Borderline Personality Disorder in Adolescence, using the Depressive Experience Questionnaire (DEQ). Results: BPD patients (n = 59; mean age = 16.6 ± 1.3) scored significantly higher than healthy controls on the two DEQ sub-factors assessing the more immature forms of Interpersonal Relatedness (Neediness) and Self-definition (Self-criticism) and significantly lower on the more mature form of Self-definition (Efficacy). BPD adolescents with NSSI showed significantly higher scores on both mature and immature forms of Interpersonal Relatedness (Neediness and Connectedness) compared to BPD adolescents without NSSI. A logistic regression analysis showed that the subfactor Neediness of the DEQ was the only significant predictor of the presence of NSSI among BPD adolescents. Conclusions: The preliminary results of this study suggests that NSSI in adolescents with BPD is developmentally linked to high developmental concerns in the domain of interpersonal relatedness, which may be taken into consideration in clinical practice. More studies are necessary to better understand the relationships between NSSI and developmental psychopathology in borderline adolescents.

RESUMO

Autobiographical memory (AM) is closely linked to the self-concept, and fulfills directive, identity, social, and adaptive functions. Individuals with autism spectrum disorder (ASD) are now known to have atypical AM, which may be closely associated with social communication difficulties. This may result in qualitatively different autobiographical narratives, notably regarding social identity. In the present study, we sought to investigate this concept and develop a cognitive intervention targeting individuals with ASD. First, 13 adolescents with ASD and 13 typically developing adolescents underwent an AM interview featuring an original coding system designed to analyze the social self. We observed that the narratives produced by the ASD group focused more on the family than on extended social spheres, compared with those of the comparison group. Moreover, participants with ASD did not include themselves in the social groups they mentioned, and produced more references to others, compared with typically developing participants. Second, we designed a cognitive intervention program consisting of individual and group sessions that targeted AM. We conducted a pilot study among three adolescents with ASD aged 12, 16, and 17 years. Preliminary results showed that the program increased extra-family narrative references by the two youngest adolescents, who produced more social integration markers. Our study of autobiographical narratives yielded interesting findings about social positioning in ASD and showed how AM can be targeted in rehabilitation programs as a vector of social interaction.

RESUMO

Autism spectrum disorder (ASD) is characterized by atypical perception, including processing that is biased toward local details rather than global configurations. This bias may impact on memory. The present study examined the effect of this perception on both implicit (Experiment 1) and explicit (Experiment 2) memory in conditions that promote either local or global processing. The first experiment consisted of an object identification priming task using two distinct encoding conditions: one favoring local processing (Local condition) and the other favoring global processing (Global condition) of drawings. The second experiment focused on episodic (explicit) memory with two different cartoon recognition tasks that favored either local (i.e., processing specific details) or a global processing (i.e., processing each cartoon as a whole). In addition, all the participants underwent a general clinical cognitive assessment aimed at documenting their cognitive profile and enabling correlational analyses with experimental memory tasks. Seventeen participants with ASD and 17 typically developing (TD) controls aged from 10 to 16 years participated to the first experiment and 13 ASD matched with 13 TD participants were included for the second experiment. Experiment 1 confirmed the preservation of priming effects in ASD but, unlike the Comparison group, the ASD group did not increase his performance as controls after a globally oriented processing. Experiment 2 revealed that local processing led to difficulties in discriminating lures from targets in a recognition task when both lures and targets shared common details. The correlation analysis revealed that these difficulties were associated with processing speed and inhibition. These preliminary results suggest that natural perceptual processes oriented toward local information in ASD may impact upon their implicit memory by preventing globally oriented processing in time-limited conditions and induce confusion between explicit memories that share common details.

RESUMO

Although most of scientific knowledge in dream research is based on young adult studies, this article provides a review of the effects of normal and pathological aging on dream psychology. It starts with preliminary comments about epistemological and methodological principles of dream research, its singularities in aged persons, and the modifications of sleep physiology with age. The whole literature agrees that dream recall progressively decreases from the beginning of adulthood - not in old age - and that dream reports become less intense, perceptually and emotionally. This evolution occurs faster in men than women, with gender differences in the content of dreams. The chronological modifications could be explained partly by changes in lifestyle and attitude towards dreams in early adulthood, but mainly by modifications of sleep physiology, particularly the decrease and qualitative changes of rapid eye movement (REM) sleep. Dreams have usually little subjective importance in the mental life of aged persons. However, working with dreams can be a valuable tool for psychotherapy in the aged. According to the few existing data, patients suffering degenerative dementia dream much less than healthy aged persons. In Alzheimer's disease, this could be linked to the decrease of REM sleep, and atrophy of associative sensory areas of the cerebral cortex. Most studied aspects of dreaming in degenerative cognitive disorders are REM sleep behavior disorders, and nightmares induced by cholinesterase inhibitors. More studies are needed to better characterize the evolution of dreams with age, particularly studies performed in sleep laboratory.
